Please help me run this applet

I am using java 6

In Windows the applet runs fine

C:\> appletviwer http://charting.bseindia.com

But in Linux (UBUNTU)

$ appletviewer http://charting.bseindia.com

gives this output

java.lang.NullPointerException

at equis.metastock.MS4Java.repaint([DashoPro-V1.2-120198])

at sun.awt.X11.XCanvasPeer.setBackground(XCanvasPeer.java:95)

at sun.awt.X11.XPanelPeer.setBackground(XPanelPeer.java:79)

at java.awt.Component.setBackground(Component.java:1575)

at equis.metastock.MS4Java.init([DashoPro-V1.2-120198])

at sun.applet.AppletPanel.run(AppletPanel.java:417)

at java.lang.Thread.run(Thread.java:619)

How do I solve this?

Its very important to run this applet from linux

Any help?
